SLIDABLE FEEDINGr-TROUGH.

Specification of Letters Patent.

Patented Jan. 9, 1917.

Application filed January 1.5, 1916. Serial No. 72,229.

To all 'whom t may concern:

Be it known that I, WILLIAM A. McCon- LOUGH, a citizen of the UnitedStates of America, and resident of Webster City, Hamilton y county,Iowa, have invented a new and useful Slidable Feeding-Trough, of whichthe following is a specification.

The Object of this invention is to provide an improved construction andarrangement whereby a trough is mounted in and carried by a feeding rackand is also slidable relative to said rack, whereby it kmay be removedfrom the rack for cleaning and fillmg.

My invention'consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in my claims andillustrated by the accompanying drawing, in which- Figure 1 is a sideelevation, partly in section, showing the trough slightly withdrawnrelative to the rack. Fig. 2 is an end elevation of the trough and rackin position for use. Fig. 3 is a side elevation of the trough detachedfrom the rack. Fig. 4 is a vertical section of the trough, on anenlarged scale. Fig. 5 is a detail bottom plan showing a portion of thesupporting frame for the trough. Fig. 6 is a detail side elevationshowing the pivotal connection of the trough to its supporting frame.

In the construction of the device as shown the rack is formed with'angle iron track members 10, 11 extending lengthwise at its oppositesides above spaced cross bars 12. Marginal bars 13, 14 extend lengthwiseof the rack above the track members 10, 11, and an apex bar 15 extendslengthwise of the rack above said marginal bars and on the median lineof the device. Partition bars 16, 17 extend upwardly and inwardly fromthe marginal bars 13, 14 respectively and are fixed at their upper endsto and support the apex bar 15. Some of the partition bars, 16a, 17a,extend downwardly from the marginal bars 13, 14, to and are fixed to thetrack members 10, 11, and serve to support said marginal bars. Thepartition bars 16, are arranged in staggered relation to the partitionbars 17, so that the upper portions of the bars 16 are arranged midwayon the apex bar 15 between the ends of the bars 17. The marginal bars13, 14 are turned outwardly at one end at right angles to form lugs 13a,14a, and the apex bar 15 is turned upwardly at its, adjacent end to forma lug 15a, and said lugs are apertured and adapted for attachment to theinner face of a wall or partition such as 1S, to hold the rack firmly inposition within the inclosure of which said wall or partition forms apart. The wall or partition 18 preferably is formed with an aperture 19corresponding approximately in dimensions to the cross-section of atrough about to be described. The track members 10, 11 preferably areextended beyond the vertical plane of the lugs 13, 14a, '15% and projectout through the aperture 19 of the partition 18.

A sheet metal trough 20 is provided, preferably semi-circular incross-section, and is of such size as to be received 'readily within thelower portion of the rack above described, its top extendingapproximately to the marginal bars 13, 14. Runners 21, 22 are spacedapart and extend lengthwise beneath the trough 20, and are adapted toslide on the track members 10, 11. The runners 21, 22 are rigidlyconnected by cross-bars 23, to which they are braced by oblique braces24. Curved frames 25, corresponding to the curvature of the trough 20,are mounted on and rise from the cross-bars 23, and on one side saidframes extend clear to the top of the trough and are formed with eyes25a. Cleats 26 are fixed to the bottom of the trough, and extend on oneside to the top of the trough and are formed with eyes 26a pivotallyconnected to the eyes 25a by means of bolts 28. Thus the trough ishinged to its supporting frame on which it normally rests, and may beturned laterally through an angle, when withdrawn from the feeding rack,for the purpose of cleaning the trough. When the trough is in uprightposition on its frame it may be mounted in the feeding rack by endwisesliding movement of the runners 21, 22 on the tracks 10, 11, and saidrunners preferably are slightly upturned at one end, as shown in Fig. 3,to facilitate such movement. At the opposite end the runners 21, 22 areextended, are turned upwardly and twisted a quarter turn, and ayoke-shaped handle 27 is pivoted to their extremities, for conveniencein manual sliding of the trough.

In practical use the device is employed for feeding swine, and theadvantages in the construction and arrangement of the rack for thispurpose will be readily understood.

The rack is preferably secured to the wall of the pen or building, andthe trough may be removed by endwise sliding movement through theaperture 19, cleaned by inverting, filled, and returned to position,without the attendant entering the inclosure. After feeding, the troughmay be removed from the rack and from the pen, this preventing theanimals from gettting it filled with litter.

I claim as my invention- 1. A device of the class described, comprisinga skeleton rack adapted to be mounted in an inclosure and y'adjacentoney wall thereof, said wall having an aperture at and registering withone end of said rack, means for securing Said rack to said wall on eachside of and above said aperture, said rack being formed with asupporting track ada ted to project through said aperture, an a trough'slidingly `mounted in said track and adapted for lengthwise movementthrough the aperture of said wall, one end of said trough normallyclosing said aperture Copies of this patent may be obtained for againstthe passage of swine when said trough is in closed position in saidrack.

Q..A device of the class described, comprising a skeleton rack adaptedto be mounted in v an inclosure and adjacent one wall thereof, said wallhaving an aperture at and registering with one end of said rack, saidrack being formed with spaced tracks eX tending along its bottom andprojecting through the aperture of said wall, and a trough formed withrunners slidably mounted on said tracks for lengthwise movement throughsaid aperture, said runners being extended outwardly and upwardlythrough said aperture and provided with a handle on their outer ends,said trough normally closing said aperture in the wall.
